Sending large attachments via email is a big no-no unless the recipient is aware of the email’s size and has given the ok. There are other means than email to send large files to recipients. It would for example be possible to upload the file to one of the myriads of file hosts that offer hundreds of Gigabytes of free storage space.
Gmail, Google’s popular email service, has recently raised the attachment limit from 20 Megabytes to 25. This could be interesting for users who regularly send emails with large attachments but also for Gmail users who like to backup files by sending them to their Gmail account. The attachment limit is obviously working in both ways which means that it is possible to send emails with a size of up to 25 Megabytes but also to receive emails that stay below that limit.

The new Gmail attachment limit seems to be enabled on all Gmail accounts already unlike other changes to the email service that usually get rolled out over time. It should also be noted that users need to make sure that the recipients can retrieve emails of that size. It can happen that the email provider refuses these emails as they might be over the size limit of that email service.

Inbox.com offers 5GB* of free storage for your emails.

The default attachment size is 20MB but if you use their Email Notifier add-on, you can go to 50MB.
But the problem is that most email accounts only support 1-5MB, particularly corporate accounts. Send an email too large and it will get bounced. I’d rather someone upload their attachment to an FTP server and provide me a link to download it.
I wish Gmail would add an option to sent an email at some point in the future, like Outlook can do.
